5.5 Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram:
Remark:
PUL/DIR
- t1: ENA must be ahead of DIR by at least 5μ s. Usually, ENA+ and ENA- are NC (not connected).
- t2: DIR must be ahead of PUL active edge by 6μ s to ensure correct direction;
- t3: Pulse width not less than 2.5μ s;
- t4: Low level width not less than 2.5μ s.

6.1 Activate Edge Setting
SW1 is used for setting the activate edge of the input signal, “off” means the activate edge is the rising edge, while “on” is the falling edge.
6.2 Running Direction Setting
SW2 is used for setting the running direction, “off” means CCW, while “on” means CW.
6.3 Micro steps Setting
The micro steps setting is in the following table, while SW3 、
SW4 、 SW5 、 SW6 are all on, the internal default micro steps inside is activate,this ratio can be setting through the HISU

This drive can provide the encoder with a power supply of +5v, maximum current 80mA. It adopts a quadruplicated-frequency counting method, and the resolution ratio of the encoder multiply 4 are the pulses per rotate of the servo motor. Here is the typical connection of
10. Parameter Setting
The parameter setting method of 2HSS86H-KH drive is to use a HISU adjuster through the 232 serial communication ports, only in this way can we setting the parameters we want. There are a set of best default parameters to the corresponding motor which are care
adjusted by our engineers, users only need refer to the following table, specific condition and set the correct parameters.
Actual value = Set value × the corresponding dimension
There are total 20 parameter configurations, use the HISU to download the configured parameters to the drive, the detail descriptions to every parameter configuration are as follows:
Item |
Description |
Current loop Kp |
Increase Kp to make current rise fast. Proportional Gain determines the response of the drive to setting command. Low Proportional Gain provides a stable system (doesn’t oscillate), has low stiffness, and the current error, causing poor performances in tracking current setting command in each step. Too large proportional gain values will cause oscillations and unstable system. |
Current loop Ki |
Adjust Ki to reduce the steady error. Integral Gain helps the drive to overcome static current errors. A low or zero value for Integral Gain may have current errors at rest. Increasing the integral gain can reduce the error. If the Integral Gain is too large, the system may “hunt” (oscillate) around the desired position. |
Damping coefficient | This parameter is used to change the damping coefficient in case of the desired operating state isunder resonance frequency. |
Position loop Kp |
The PI parameters of the position loop. The default values are suitable for most of the application, you don’t need to change them. Contact us if you have any question. |
Position loop Ki |
Speed loop Kp |
The PI parameters of the speed loop. The default values are suitable for most of the application, you don’t need to change them. Contact us if you have any question. |

Open loop current |
This parameter affects the static torque of the motor. |
Close loop current | This parameter affects the dynamic torque of the motor. (The actual current = open loop current +close loop current) |
Alarm Control |
This parameter is set to control the Alarm optocoupler output transistor. 0 means the transistor is cut off when the system is in normal working, but when it comes to fault of the drive, the transistor becomes conductive. 1 means opposite to 0. |
Stop lock enable |
This parameter is set to enable the stop clock of thedrive. 1 means enable this function while 0 means disable it. |
Enable Control |
This parameter is set to control the Enable inputsignal level, 0 means low, while 1 means high. |

11. Processing Methods to Common Problems and Faults
11.1 Power on power light off
n No power input, please check the power supply circuit. The voltage is too low.
11.2 Power on red alarm light on
n Please check the motor feedback signal and if the motor is connected with the drive.
n The stepper servo drive is over voltage or under voltage. Please lower or increase the input voltage.
11.3 Red alarm light on after the motor running a small
angle
n Please check the motor phase wires if they are connected correctly, if not, please refer to the 3.4 Power Ports
n Please check the parameter in the drive if the poles of the motor and the encoder lines are corresponding with the real parameters, if not, set them correctly.
n Please check if the frequency of the pulse signal is too fast, thus the motor may be out of it rated speed, and lead to position error.
11.4 After input pulse signal but the motor not running
n Please check the input pulse signal wires are connected in reliable way.
n Please make sure the input pulse mode is corresponding with the real input mode.
